I have a system with a Q6600, P6N Diamond MB, 4GB RAM, and 2 8800GTX’s. Power consumption just after boot at idle is around 230W. Consumption increases (as expected) when running a CUDA program, but does not decrease to idle levels after the program completes - it hovers around 330W until rebooting.
I’ve found this happens with the first execution of any CUDA program after booting. Simply loading the driver module does not increase power consumption.
Our product may spend a significant amount of time powered on and idle, so I would certainly like to reduce power consumption as much as I can. Is there a way I can “clean up” after executing to help?
